PROBLEM TO BE SOLVED: To provide a cycle for travel training which has enhanced strength of a connection part, improved accuracy of production and assembly, and which simplifies connection work.SOLUTION: A body connection part 21 of a cart body 2 of a cycle 1 for travel training comprises a cylindrical surfaces 211, 212 on both sides of a cross direction, namely a travel direction, and a pair of penetration holes 21a, 21b for penetrating to bolts 4 are formed on the cylindrical surfaces 211, 212 and the cylindrical surfaces are formed into a cylindrical shape which is a regular hexagonal shape in plan view, in which corners 21c which are formed by plastic working are provided on left and right both sides. A unit connection part 34 of a pedal unit 3 is formed into a cylindrical shape corresponding to the body connection part 21 such as cylindrical surfaces 341, 342 on both sides of the cross direction, penetration holes 34a, 34b and a corner 34c, and when the unit connection part 34 is connected to the body connection part 21, twisting in the travel direction is prevented by the bolt 4, and twisting from the lateral direction is prevented by the corner 34c of the unit connection part 34 and the corner 21c of the body connection part 21. |
